"There's a chance I could play again this season, but this is not an arm, not a foot," Donnell said. "This is my neck. I've broken arms, broken legs and I knew they were broken. This is a neck, so we just have to be really careful."

Donnell, 27, has missed the last two games and couldn't get back into form despite the bye. He has 29 catches for 223 yards and two touchdowns this season.

The Giants previously put fellow tight end Daniel Fells on injured reserve with a staph infection.

"Hopefully he can knock the rust off really quick in the game and he can help us," Spagnuolo said of Amukamara, who missed the past five games due to a pectoral tear.

Spagnuolo also noted that the Giants will need rookie safety Landon Collins to rebound from his missed interception attempt against the Patriots, when he went airborne but couldn't come down with the ball. Asked whether Collins remained confident despite the drop, Spagnuolo noted that Collins was a former Alabama player and that he kept his pride.

Left guard Justin Pugh (concussion) and linebacker Mark Herzlich (quad) were ruled out for Sunday. Center Weston Richburg (high ankle sprain) was listed as doubtful. Dallas Reynolds is the only center on the active roster, and Tom Coughlin did not say whether or not he would consider adding another center before the game.
